FOUNTAIN AND FEED ATTACHMENT FOR WRITING-PENS.

SPECIFICATION forming part of Letters Patent No. 389,156, dated September 4-, 18.88.

Application filed November I l, 1887. Serial No. 255,140.

To all whom it may concern.-

Be it known that I, JOHN H. Konnro, ofOincinnati, Hamilton county, Ohio, have invented a new and useful Fountain and Feed Attachment for \VritingPens, of which the following is a specification.

My invention consists ofa peculiarly-formed india-rubber nipple or capsule, which, being drawn over the nib and holder, serves as an ink reservoir or fountain and feeder, from which, 111 and by the act of writing, the point of the pen is kept automatically charged with ink. The orifice through which the point of the pen protrudes is so formed as to afford an inlet through the body of ink for the air which is required to correct the tendency to vacuum created by escape of ink in the act of writing.

A distinguishing valuable characteristic of my device is that it affords a means of cheaply and easily converting any ordinary pen into a fountain-pen.

In the accompanying drawings, Figure I is an under side view of my nipple or capsule. Figs. II, III, and IV are respectively an up per side View, an under side view, and an 2tX- ial section of an ordinary writing-pen with my fountain attachment. Figs. V and VI respectively show two methods of charging the capsule. Fig. VII shows my capsule applied to a tubularhandle. Fig. VIII represents my capsule provided with a rear orifice for re ception of the point of a nib whose main body is designed to be external to said capsule. Fig. IX represents such capsule in place upon the pen.

1 2 3 may respectively represent an ordinary metallic nib or pen proper, the holder thereof, and a wooden or other handle.

4 is my india-rubber capsule, having the represented cylindrical body I and the conical head 4.", obliquely truncated at its point so as to expose an oblique orifice, 4, whose form and dimensions are such as, by covering the slit 1 on its upper side almost to the point, to facilitate the delivery of ink, and such as to leave underneath the inserted nib room for entrance of occasional minute globules of air to correct the tendency to vacuum created in the upper part of the capsule I orink-chamher by the escape of ink through the slit 1 of (No model.)

the pen in the operation ofwriting. Thepaths ot' the outfiowing stream of ink and of the entering globules 01' air, respectively, are indicated by strong and dotted arrows. The size of the rear opening, 4 of the capsule is such as to cause it to so tightly inclasp the penhandle as to forbid entrance of air at that part.

The capsule may be charged by any suitable 1neansfor example, by a syringe-as shown at 7 in Fig. V, or, while the point of the pen is immersed in the ink, first pressing the capsule against and then withdrawing it from a suitable projection from the inner wall of the inkstand neck. Such projection may be a protuberance integral with the substance of 6 the inkstand, or may consist of any other suitable devicc-such, for example, as a saddleformed clip, 8, capableof being engaged over the rim of the inkstand in the manner shown in Fig. VI.

The above-described preferred and simplest form of my invention may be associated with the other features-as, for example, the pen handle being tubular, as in Fig. VII, and communicating interiorly with the interior of the capsule, a larger ink-chamber is thereby secured. A nick or incision, 4", in the back of the capsule may permit insertion of the point of the nib whose main portion is external to the capsule, and such capsule may, instead of embracing the handle, be arranged interiorly thereof, as represented in Fig. IX.

I have described my capsule or nipple as composed .of india-rubber, that being the material successfully employed by me for the purpose, but reserve the right to employ any sub stance that will possess the necessary qualities of imperviability and elasticity.

The above-described device is radically different in construction and mode of operation from previous devices for the purpose,in which the nipple-orifice is formed to closely embrace the pen-nib, and in which the only means of relieving the vacuum in the ink-chamber is by special air-inlet from the rear through a specially-constructed tubular handle, and not at the pen-point, as in my herein-described improvement, in which the ink-feeding and airsupply both take place through the nippleorifice 4'.

ICO

I claim as new and of my invention 1. The combination, with an ordinary pen having an ordinary holder, of a capsule fitted on and entirely closed at its top by the end of 5 said holder, and provided with a perforation through which projects the nib of the pen, said perforation being large enough to leave an opening between the nib of the pen, and one side of the perforation, thereby forming a com- :o bined single inlet for air and outlet for ink, substantially as and for the purpose set forth.
